I have extracted the information from these two separate individuals and their BDM record and posted all the information in another message elsewhere.
The similarities between these two different individuals is very confusing for family researchers, as follows.
They both died in the same year 1888.
They both married a Johnston, 1, John Johnston and 2, William Johnston.
They were both christened as an Isabel. However, 2 referred to herself as Isabella for the rest of her life.
The middle initial of M for 1 is Maria, there is absolutely no records that give 2 a middle name or middle initial, at this point in time.
What also is adding to the confusion is that on sites like Familysearch.org, 2, is given a father's first name as Fredrick Cunningham, when it should be Robert Cunningham, as from Scotland Births and Baptisms records.
Whilst 1 father's name is actually Frederick Hughes.
